CASE PRlNTlNG AND EMBosslNG MACHINE.

SPECIFICATION forming part Yof Letters Patent No. 293,797, datedFebruary 19, 1884.

Application filed February 2, 1883. (No model.)

lo au whom it may concern.-

Be it known that I, HENRY F. SHEPHERD, of the city of Philadelphia,county of Philadelphia andState of Pennsylvania, have invented anImprovement in'Case Printing and Ernbossing- Machines, of which thefollowing is a specification. l

My invention has reference to case printing and embossing machines, butmore particularly to that class of machines especially adapted forprinting book covers or cases; and it consists in certain vimprovementsin the wellknown Buggles printing-press patented N ovember 10, 1&40, bywhich it is converted into a completely organized case or lightembossing machine, as fully set forth in the following specification,and shown in the accompanying drawings, which form part thereof. Theobject of myinvention is to so construct and arrange the parts ofamachine of this class that the strains due to the impression arereceived by suitable supports in such a manner that no matter where thetype or form may be placed on the form-plate there is no possibility ofdisplacement or uneven impression; further, to provide suitable supportsfor the impression plate, Vwhereby it may be adjusted vertically withoutincreasing its upward movementand to provide the receiving-plate withadjustable guides wherewith to insure proper registration of thebook-cases placed thereon.

In the drawings, Figure lis a sectional side elevation of a machineembodying my improvements, taken on line x @c of Fig. 2. Fig. 2 is afront sectional elevation of same on line y y of Fig. l. Fig. 3 is aplan view of the receivingplate, and shows the guide or registeringdevices; and Fig. 4L is a cross-section of the registering device online z z of Fig. 3.

A is the frame of the machine, and is pro- 'vided at the top withhorizontal guideways A',

in which carriage B slides,v the latter carrying loosely supportedthereon the receiving-plate C, which is prevented from slippingbackwardby a rib or bar, b. The carriage B carries on its other end one or moreinking-rollers, Bf, adapted to vertical movement. This carriage B isreciprocated byA an arm, D, connected thereto at the top by alink, d,and secured to a rock-shaft, D,`carried inthe frame A, and actuated byan arm, D2, carrying a roller, d',

which works in cam-groove e in the face of cam-wheel e, which is' drivenby a spur-wheel, E, and a pinion, E', on apshaft, E2, the latter beingrotated byband-wheels E, and steadied by a iiy-wheel, F.

Secured to the frame A on each side, and to the rear of thereceiving-plate7 are four heavy vertical bolts, G, provided on theirtops with nuts g and washers g. Y The form-plate I-I is pivoted at h tothe frame A or an extension therefrom, and is supported on the other endby pins or lugs h, so as to lie-horizontally between the four bolts Gand sufficiently high that when form H is glued or otherwise secured tothe under side thereof it shall be inked by the passing rollers B. Thisformer-plate is re-enforced on the upper side with heavy hubs h2 andribs h3, toprevent any bending or springing thereof', and is clampeddown in position by housings I, two in number, which eX- tend across theupper face of the hubs of said plate and iit around thev bolts G byslots t' under nuts g. Immediately below said formerplate is theimpression-plate J, which is guided by two downwardly-extendingguide-rods, J', which work through v holes j in the frame Aor extensionstherefrom. The bottom of this plate is hinged to the arm K, by which ritis actuated, the said arm having its bottom notched at 7c, so as tocatch upon a pin or lug, L, carried by ahub, M, made fast to a shaft, N.The shaft revolves in Vbearings n, which may be open at the top, and hassecured to it the gear-wheel E and cam-wheel e. The arm K is caused toswing out of reach of the pin L by strap or chain O, which passes over aguide, O', and carries aweight, O2, and may be pulled into operatingposition by a strap, P, having one end secured to the periphery of wheelP', secured toa shaft rotated by handle p.v The impression-plate J isprovided on the bottom with stop-pins S, which rest upon the lugs T offrame A, and by which the downward movement of the plate J may bereduced by the interposition of metal pieces t or by increasing thelength of said pins, and also relieves all Wear from the under side ofsaid plate.

Q is an vink-carrying roller, to ink the inking-rollers B. Thereceiving-plate C is provided with an l.. -shaped guide, R, which is T-slotted, as at r', the longer leg having a loose re-enforcing slide, r',to prevent springing of saidlong slotted leg. There are three or moreIOO additional slide blocks, rl, to which are adagainst the form ortypeH, which is held im justably pivoted by screws fr theregisteringerms 1'", having slots r. The guide R- is secured to theplate C by screws l', and maybe set to or from the center of the plate;but by the use of arms r and the double housings I this is notnecessary, as the pressure given to the impression is equal over theentire surface of the receiving-plate- Y rlhe operation is as follows:The book ense 01 cover V being; placed in position upon thereceiving-plate G and brought to the proper register, the l1 andlep ispulled, which throws the arm K into position to be @ought by the pin L.Prior thereto, however, the conigroove e' causes the arm D to be movedforward, causing the carriage and its plate@ to move to :t positionimmediately below the form-plate H, where itcomcs to rest, und duringsaid period of rest the hiking-rollers take fresh ink, :md the arm Kraises the impression-plate J and the receiving-plate Cwith its ense orcover, causing the latter to be pressed movztbleby theherrvy doublehousingsl I. The said plates with the printed or embossed cover thendescend, the impression-plate resting on its stop-pins. As soon as thearm K is freed again, the weight O causes its end to be drawn over tothe other side and in position for another impression. The carriage isthen moved back and a new case or cover placed upon the plate C, theprinted one having been removed.

Having now described my invention, what I claim as new, end desire tosecure by Letters Patent, is

The combination of theimpressioirplote, its guide-pins, guide-lugs, andstoppins, substantinlly as and for the purpose specified.

In testimony of which invention I hereunto set my lmnd.
